reformatted HD has problems

Long story short, I've reformatted my HD via the XP installation disk and installed XP again when it screwed up. It actually warns you that installing an OS over another may result in problems which it already has.

I d/l'ed SeatoolsDOS.iso but there weren't any directions...big surprise.I have a feeling I'm supposed to burn this to a cd and it boots from there. Too bad I don't have any cd's around....just DVD's.I suppose I could set the BIOS to boot to my DVD drive...Yaaaaaaawn
